This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

2 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…
  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Carta operates in the finance and technology sectors, providing SaaS solutions for equity and fund management. Their business model focuses on subscription-based software services for private companies and investment firms. The company targets a sophisticated audience including startups, venture capitalists, and fund managers. Carta's competitive advantage lies in its end-to-end platform that integrates compliance, valuations, and fundraising support. The website content and structured data indicate a large enterprise with a global footprint, supported by a consistent brand and active social media presence. Partnerships and community engagement are evident through linked domains and resources. The company appears to have a strong growth trajectory and a well-established market presence.

Security posture

Carta's website employs HTTPS with a valid SSL configuration and uses Cloudflare DNS, enhancing security and performance. Security headers are likely implemented, and the domain status clientTransferProhibited prevents unauthorized transfers. The site uses OneTrust for cookie consent, indicating GDPR compliance. However, DNSSEC is not enabled, which could be an area for improvement. No explicit security policy or incident response contact information is found, which is a gap in transparency. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is strong but could benefit from publishing formal security policies and enabling DNSSEC.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Publish a dedicated security policy page outlining security practices and controls.
  3. Provide clear incident response contact channels such as security@ or abuse@ emails.
  4. Consider implementing and publishing a vulnerability disclosure or security.txt file.
  5. Maintain and regularly audit third-party scripts and tracking tools to minimize risk.

Technical notes

Notes

The website is built using modern web technologies including SvelteKit, which supports fast and efficient rendering. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site integrates marketing and analytics tools such as Google Tag Manager and Marketo, and uses OneTrust for privacy compliance. Performance is optimized with preloading fonts and scripts, lazy loading images, and modular JavaScript. Accessibility and SEO best practices are observed with proper meta tags, structured data (JSON-LD), and responsive design. No major technical debt or outdated libraries were detected. The technical infrastructure supports a high-quality user experience and robust business operations.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
